Abstract:
Sampling is so deep-rooted in our habits that it usually takes place unconsciously. A large number of books and articles have been published in this field. The connection between sampling and quality control is the reason that many industries have focused their attention on sampling; however, only a few numbersare familiar with bulk material sampling related issues. Describing this theory along with its seven errors is the main object of this research. Using this theory, characteristics of the lot of interest was analyzed. Creating necessary conditions for assuring sampling correctness is very critical and if these conditions cannot be provided, implementing some part of the theory issues will be disturbed. This theory is applied for all solid materials, liquids, and gases, but its literature is very limited. Due to its wide spread applications, only liquid sampling was investigated. In fact, edible oil sampling process case study was analyzed to present a general solution in order for providing a sampling procedure
